[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The following is combined Figures 1-3 The electronic device provided by the utility model embodiments will be described in detail through specific implementation examples and application scenarios.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the present invention provides an electronic device, including: a host 1 and a slave 2; The host 1 includes a first electrical connection port 11, a second electrical connection port 12, a first circuit board 13 and a first battery 14. The first circuit board 13 is electrically connected to the first electrical connection port 11, the second electrical connection port 12 and the first battery 14 respectively. The first electrical connection port 11 is configured to be electrically connected to a power adapter. The sub-unit 2 includes a third electrical connection port 21, a second circuit board 22, and a second battery 23. The second circuit board 22 is electrically connected to the third electrical connection port 21 and the second battery 23 respectively. When the electronic device is in its complete state, the second electrical connection port 12 and the third electrical connection port 21 are plugged in to enable communication and charging connection between the host 1 and the slave device 2. When the electronic device is in a split state, the second electrical connection port 12 and the third electrical connection port 21 are separated from each other.

[0025] It is understandable that the host 1 and the slave 2 communicate and charge through the second electrical connection port 12 and the third electrical connection port 21. The second electrical connection port 12 and the third electrical connection port 21 use the same type of interface and are both equipped with communication signal transmission channels and charging signal transmission channels.

[0026] The first electrical connector 11, the second electrical connector 12, and the third electrical connector 21 can all use Type-C interfaces; for example, the first electrical connector 11 and the second electrical connector 12 are both Type-C female connectors, and the third electrical connector 21 is a Type-C male connector. When both the second electrical connector 12 and the third electrical connector 21 are Type-C interfaces, the second electrical connector 12 and the third electrical connector 21 can be plugged into each other and can communicate based on the USB 2.0 protocol.

[0027] In practical applications, both the first circuit board 13 and the second circuit board 22 can be PCB boards, and both the first battery 14 and the second battery 23 can be lithium batteries known in the art. The first circuit board 13 can be provided with a charging management circuit for charging the first battery 14 based on the first electrical connection port 11, and the second circuit board 22 can be provided with a charging management circuit for charging the second battery 23 based on the third electrical connection port 21.

[0028] The electronic device shown in this utility model has a first circuit board 13 and a first electrical connection port 11, a second electrical connection port 12 and a first battery 14 connected to the first circuit board 13, and a second circuit board 22 and a third electrical connection port 21 and a second battery 23 connected to the second circuit board 22. The second electrical connection port 12 and the third electrical connection port 21 can be plugged in, so that the entire electronic device is in a complete state for convenient carrying. When charging is required in this state, simply connect the first electrical connection port 11 to the power adapter. At this time, the external power can charge the first battery 14 of the main unit 1 through the first electrical connection port 11. Since the second electrical connection port 12 and the third electrical connection port 21 are plugged in, the first battery 14 can also charge the second battery 23 of the sub-device 2 through the second electrical connection port 12 and the third electrical connection port 21. When it is not necessary to charge the sub-device 2, simply separate the second electrical connection port 12 and the third electrical connection port 21, so that the entire electronic device is in a split state. Its operation is simple and convenient.

[0029] As can be seen from the above, the electronic device shown in this utility model is convenient to carry in its entirety based on the plug-in cooperation of the second electrical connection port 12 and the third electrical connection port 21, ensuring a stable communication and charging connection between the host 1 and the slave 2. By using a power adapter connected to the first electrical connection port 11, the host 1 and the slave 2 can be charged simultaneously, improving the convenience of charging.

[0030] In some embodiments, such as Figure 3 As shown, the first circuit board 13 is provided with a first processing module, a first charging management module, a voltage output module and an insertion device identification module; the second circuit board 22 is provided with a pull-down circuit, and the third electrical connection port 21 is grounded through the pull-down circuit; The first electrical connection port 11 is electrically connected to the first charging management module. The first charging management module is electrically connected to the first processing module and the first battery 14. The first battery 14 is electrically connected to the second electrical connection port 12 through the voltage output module. The first processing module is electrically connected to the first voltage output module and is electrically connected to the second electrical connection port 12 through the insertion device identification module. When the second electrical connection port 12 and the third electrical connection port 21 are plugged in, the insertion device identification module is configured to be grounded via a pull-down circuit to feed back a trigger signal to the first processing module. The first processing module is used to control the voltage output module to start voltage output according to the trigger signal.

[0031] It is understood that the first processing module includes a central processing unit (CPU) and a power management chip (PMIC), and the CPU and the PMIC are communicatively connected; the first charging management module can use a charging chip known in the art. A charging chip is an integrated circuit specifically designed for battery charging management. Its core task is to safely and efficiently convert external power sources (such as USB or adapters) into voltages and currents suitable for the battery and control the entire charging process.

[0032] For example, when the first electrical connection port 11 is a Type-C interface, the first electrical connection port 11 has USB3.1 and AUX pins, CC1 / CC2 pins and VBUS pins. The USB3.1 and AUX pins of the first electrical connection port 11 are electrically connected to the central processing unit (CPU), and the CC1 / CC2 pins of the first electrical connection port 11 are electrically connected to the CC1 / CC2 pins on the power management chip (PMIC).

[0033] The first charging management module has a VBUS pin, a VSYS pin, and a VBAT pin. The VBUS pin of the first electrical connection port 11 is electrically connected to the VBUS pin of the first charging management module. The VSYS pin of the first charging management module is electrically connected to the VSYS pin on the power management chip (PMIC). The VBAT pin of the first charging management module is electrically connected to the first battery 14.

[0034] The voltage output module can use a BOOST boost chip. The voltage output module has a VBAT pin, an EN pin, and a level output pin. The VBAT pin of the voltage output module is electrically connected to the first battery 14, the EN pin of the voltage output module is electrically connected to the central processing unit (CPU), and the level output pin of the voltage output module is electrically connected to the second electrical connection port 12.

[0035] Both the second electrical connection port 12 and the third electrical connection port 21 can use Type-C interfaces and both have VBUS pins, SBU1 pins, and CC1 / CC2 pins. The inserted device identification module can use a CC logic chip. The VBUS pin of the second electrical connection port 12 is electrically connected to the level output pin of the voltage output module. The SBU1 pin of the second electrical connection port 12 is electrically connected to the central processing unit (CPU). The CC1 / CC2 pins of the second electrical connection port 12 are electrically connected to the CC1 / CC2 pins of the CC logic chip. The IIC / INT pins of the CC logic chip are electrically connected to the GPIO pins of the central processing unit (CPU).

[0036] A pull-down circuit can be formed by connecting multiple resistors in series and parallel. Of course, a pull-down circuit can also be formed by a single resistor.

[0037] In practical applications, when the second electrical connection port 12 and the third electrical connection port 21 are not plugged in, the device identification module will not detect voltage fluctuations caused by the grounding of the pull-down circuit. At this time, the device identification module will not send a trigger signal to the first processing module, and the first processing module will not control the voltage output module to start voltage output. Conversely, when the second electrical connection port 12 and the third electrical connection port 21 are plugged in, based on the trigger signal from the device identification module, the first processing module will determine that the second electrical connection port 12 of the host 1 and the third electrical connection port 21 of the slave device 2 are plugged in, rather than the second electrical connection port 12 of the host 1 being plugged in with other interfaces. At this time, the first processing module will control the voltage output module to start voltage output based on the trigger signal, so that the host 1 can charge the slave device 2.

[0038] In some embodiments, such as Figure 3 As shown, the second circuit board 22 is also provided with a second processing module and a second charging management module; the third electrical connection port 21 is electrically connected to the second charging management module and the second battery 23, and the second charging management module and the second processing module are electrically connected.

[0039] The second processing module can be a central processing unit (CPU) and a power management chip (PMIC) that are communicatively connected in the above embodiments. The second charging management module can be a charging chip in the above embodiments. The charging chip is electrically connected to the third electrical connection port 21, the second battery 23 and the power management chip (PMIC).

[0040] In some embodiments, such as Figure 3 As shown, the first electrical connection port 11 is communicatively connected to the first processing module, the first processing module is communicatively connected to the second electrical connection port 12, and the third electrical connection port 21 is communicatively connected to the second processing module.

[0041] It is understandable that since the first electrical connection port 11 is connected to the first processing module, external devices can establish a communication connection with the host 1 through the first electrical connection port 11.

[0042] Since the first processing module and the second electrical connection port 12 are communicatively connected, and the third electrical connection port 21 and the second processing module are communicatively connected, the host 1 and the slave 2 can establish a communication connection when the second electrical connection port 12 and the third electrical connection port 21 are plugged in. In practical applications, when the insertion device identification module is configured to be grounded through a pull-down circuit, the insertion device identification module will feed back a trigger signal to the first processing module. The first processing module is used to control the signal switch to be turned on according to the trigger signal, so that the first processing module can communicate with the second electrical connection port 12 through the turned-on signal switch.

[0043] For example, when the first electrical connection port 11, the second electrical connection port 12, and the third electrical connection port 21 all adopt Type-C interfaces, the D+ / D- pins of the first electrical connection port 11 are electrically connected to the D+ / D- pins of the power management chip (PMIC) corresponding to the first processing module to realize signal transmission between the first electrical connection port 11 and the first processing module; the D+ / D- pins of the power management chip (PMIC) corresponding to the first processing module are electrically connected to the D+ / D- pins of the second electrical connection port 12 to realize signal transmission between the first processing module and the second electrical connection port 12.

[0044] When the second electrical connection port 12 and the third electrical connection port 21 are plugged in, the D+ / D- pins of the second electrical connection port 12 and the third electrical connection port 21 are electrically connected to realize signal transmission between the second electrical connection port 12 and the third electrical connection port 21. The D+ / D- pins of the third electrical connection port 21 are electrically connected to the D+ / D- pins of the power management chip (PMIC) corresponding to the second processing module to realize signal transmission between the third electrical connection port 21 and the second processing module.

[0045] In some embodiments, such as Figure 3 As shown, the host 1 is equipped with a first microphone 15, a first speaker 16 and a first wireless communication module 17, and the first microphone 15, the first speaker 16 and the first wireless communication module 17 are electrically connected to the first circuit board 13 respectively. The sub-unit 2 is equipped with a second microphone 24, a second speaker 25, and a second wireless communication module 26. The second microphone 24, the second speaker 25, and the second wireless communication module 26 are electrically connected to the second circuit board 22, respectively. The first wireless communication module 17 and the second wireless communication module 26 are communicatively connected. The first circuit board 13 is configured to translate the voice information collected by the first microphone 15, and the second circuit board 22 is configured to translate the voice information collected by the second microphone 24.

[0046] Understandably, the first microphone 15 can be a microphone array used to collect voice information. The first circuit board 13 is equipped with a first voice recognition module and a first translation module. The first microphone 15 is electrically connected to the first voice recognition module, the first voice recognition module is electrically connected to the first translation module, and the first translation module is electrically connected to the central processing unit (CPU) corresponding to the first processing module. The first microphone 15, the first speaker 16, and the first wireless communication module 17 are each electrically connected to the central processing unit (CPU) corresponding to the first processing module. The first voice recognition module is used to recognize the voice information collected by the first microphone 15, and the first translation module is used to translate the information recognized by the first voice recognition module.

[0047] Accordingly, the second microphone 24 can be a microphone array, and the second circuit board 22 is equipped with a second speech recognition module and a second translation module. The second microphone 24 and the second speech recognition module are electrically connected, the second speech recognition module and the second translation module are electrically connected, the second translation module and the corresponding central processing unit (CPU) of the second processing module are electrically connected, and the second microphone 24, the second speaker 25 and the second wireless communication module 26 are respectively electrically connected to the corresponding central processing unit (CPU) of the second processing module. The second speech recognition module is used to recognize the speech information collected by the second microphone 24, and the second translation module is used to translate the information recognized by the second speech recognition module.

[0048] The first wireless communication module 17 and the second wireless communication module 26 can both be Bluetooth modules or WiFi modules, and there is no specific limitation on this.

[0049] In practical applications, electronic devices are used as translators. When the electronic device is in a split state, for the first user and the second user who are from different countries and cannot communicate directly, the first user can hold the main unit 1 and the second user can hold the sub-unit 2 to conduct voice communication over a certain distance.

[0050] For example, after the voice information emitted by the first user is collected by the first microphone 15, the first circuit board 13 translates the voice information collected by the first microphone 15 and controls the translated information to be wirelessly transmitted to the second wireless communication module 26 of the slave unit 2 through the first wireless communication module 17. After receiving the translated information transmitted by the second wireless communication module 26, the second circuit board 22 of the slave unit 2 controls the second speaker 25 to perform voice broadcast so that the second user can recognize it.

[0051] Correspondingly, after the second user's voice information is collected and translated by the slave unit 2, it can be sent to the host unit 1 via the second wireless communication module 26. The host unit 1 will control the first speaker 16 to broadcast the voice so that the first user can recognize it.

[0052] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the host 1 is also provided with a first display screen 18, which is communicatively connected to the first circuit board 13; and / or, the slave unit 2 is also provided with a second display screen 27, which is communicatively connected to the second circuit board 22.

[0053] The first display screen 18 is used to display the translation information obtained by the first circuit board 13 after translating the voice information collected by the first microphone 15, and the second display screen 27 is used to display the translation information obtained by the second circuit board 22 after translating the voice information collected by the second microphone 24.

[0054] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the sub-unit 2 is also equipped with a start button 28, which is electrically connected to the second circuit board 22. The start button 28 is used to receive a press input to output a translation start command to the second circuit board 22. The second circuit board 22 is used to translate the voice information collected by the second microphone 24 according to the translation start command.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the main unit 1 includes a first housing, a first electrical connection port 11, a second electrical connection port 12, a first circuit board 13 and a first battery 14 respectively disposed in the first housing; the sub-unit 2 includes a second housing, a third electrical connection port 21, a second circuit board 22 and a second battery 23 respectively disposed in the second housing; The width of the first housing is adapted to the width of the second housing, and the second electrical connection port 12 and the third electrical connection port 21 are inserted along the length direction of the first housing.

[0056] It is understandable that, for the host 1, the first electrical connection port 11 is located on the length side of the first housing, the second electrical connection port 12 is located on the width side of the first housing, and the first circuit board 13 and the first battery 14 are respectively located inside the first housing.

[0057] For the sub-unit 2, the third electrical connection port 21 is located on the width side of the second housing, and the second circuit board 22 and the second battery 23 are respectively located inside the second housing; when the second electrical connection port 12 and the third electrical connection port 21 are plugged in, the first housing and the second housing are arranged side by side along the length direction of the first housing.

[0058] In this embodiment, Figure 1 and Figure 2 The diagram shows that the first electrical connection port 11 and the second electrical connection port 12 are both Type-C female connectors, and the third electrical connection port 21 is a Type-C male connector. This arrangement ensures the aesthetic appearance of the main unit 1 and facilitates the plugging and unplugging of the sub-unit 2.

[0059] In practical applications, the third electrical connection port 21 is configured to be movably disposed on the width side of the second housing to switch between a first state extending outside the second housing and a second state retracted inside the second housing. The third electrical connection port 21 can be configured to be slidably or rotatably connected to the second housing.

[0060] The width side of the second housing can be provided with a slot, and the third electrical connection port 21 can be provided at the bottom of the slot. When the second electrical connection port 12 and the third electrical connection port 21 are inserted along the length direction of the first housing, the width side of the first housing can be engaged in the slot to ensure the reliability of the connection between the host 1 and the slave 2.

[0061] Alternatively, a storage slot can be provided on the back of the first housing. The storage slot is compatible with the second housing, and when the second electrical connection port 12 and the third electrical connection port 21 are separated, the entire sub-unit 2 can be stored in the storage slot.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
